Seeed Base Shield V2 User manual
Arduino Uno is the most popular Arduino board so far, however it is sometimes frustrating
when your project requires a lot of sensors or Leds and your jumper wires are in a mess. The
purpose of creating the Base Shield is to help you get rid of bread board and jumper wires.
With the rich grove connectors on the base board, you can add all the grove modules to the
Arduino Uno conveniently! The pinout of Base Shield V2 is the same as Arduino Uno R3.
